B450 Dual GPU? Bifurcation?
You're considering adding a second GPU to your Mortar Max for tasks like Blender rendering and photogrammetry. The system will only support PCIe 4x through the chipset, which isn't ideal for dual GPUs. Make sure your motherboard can handle that configuration and check if your future plans align with this setup. You'll need a board that supports dual GPUs, such as an X570 or similar, and you may need to modify the PCIe slots accordingly.
Technically, yes—it doesn't include a PLX chip, but the bottom slot likely supports X4 lanes as mentioned.
You'd want boards with powerful graphics capabilities, ideally featuring dedicated GPUs or strong integrated graphics support for full utilization.
For a slot with eight lanes, consider models such as X570 or X470.
Most x570 and x470 boards will work with this, which matches what the chipset is designed to handle. It’s a known feature of the board itself.
they hold the secondary position as x8 when searching for an x570 board similar to the x570 TUF from the X570-P or Prime Pro, unless you opt for Intel, where Z490 and Z390 would also be viable choices.
Check the specs carefully for the exact model number. Confirm whether it's 16x4 or 8x8. Also, see what compatibility requirements are listed—especially regarding SLI support.
